Bhutanese archers have known for generations that arrows fly differently as the day warms up. They just couldn't explain why — until now. 🎯
New research from The University of Queensland and the Royal Thimphu College in collaboration with Archery Australia found daily changes in air density, driven by rising temperatures, can shift arrow landing points by up to 40 centimetres in Bhutanese archery, the Himalayan kingdom's national sport.
UQ lead researcher, Dr Boyd Wright from the School of the Environment said the study was the first to empirically examine air density's effect on arrow trajectory in any form of archery.
Bhutanese archery is a long-range form of archery in which arrows are shot over distances of approximately 145m.
For archers who had spent careers adjusting by instinct and feel, the research offers a breakthrough framework for integrating air-density effects into stronger archery performance. 🏹
